Where are module variables, parameters, and temporary variables introduced and initialized in a program?
TEMPORARY VARIABLES :
INTRODUCED : inside a block, they have very short lifetime and hold data that can be discarded or is later stored in a permanent variable
INITIALIZED : temporary variables can be initialized anywhere inside the block where they are declared.
PARAMETERS:
INTRODUCED : parameters are declared inside the parenthesis of the function definition
INITIALIZED : parameters can be initialized where they are declared or can be declared in the parenthesis of the function call
MODULE VARIABLE :
INTRODUCED : A module-level variable is declared for a particular module. It is available to all procedures within that module but not to the rest of the application. Module-level variables remain in existence for the lifetime of the application and preserve their values.
INITIALIZED : module variable gets initialized where they are declared inside the module. it is initialized to 0 by default.

Convert the following assembly language program into a C program: *Update: The variables are initialized, in lines 4 & 6 of the red assembly language code. Convert the following assembly language program into a C program: *Update: The variables are initialized, in lines 4 & 6 of the red assembly language code. include "p24Hxxxx.inc" global__reset bss: Uninitialized data section: Variables start at location 0x0800 x: .space 2: Allocating space (two bytes) to variable. y: .space 2;Allocating space (two bytes) to...
Answer this asap Variables initialized inside a MATLAB function are local to the function and are not available outside of the function. TRUE or FALSE
ume that x and y are boolean variables and have been properly initialized. &х Which of the following always evaluates to the same variable as the expression above? a.) x b.) y
5. The following function uses reference variables as parameters. Rewrite the function so it uses pointers instead of reference variables, and then demonstrate the function in a complete program. int pointe rFun (int int temp-xi y - temp * 10; &x, int &y) return x + y; Copy and paste your program into the word document. Capture the output window demonstrating your function works directly below the program.
2. Consider the following two equations where all the parameters are non-zero. The two variables ri and r2 are assumed to be exogenous (a) Write down conditions under which the system is simultaneous equations system (2 marks) (b) Suppose the conditionsin (a) hold. What is the identification status of y equa tion (first equation)? How about the identification status of y2 equation (second equation)? (4 marks) 2. Consider the following two equations where all the parameters are non-zero. The two...
Assume x and y are boolean variables that were declared and initialized correctly. Regardless of the initial values for x and y, which Java statement is logically equivalent to all of the Java source code below? boolean z = false; if (!x) N = true; else if (x && Y) Z = true; = !x || Y; N = x || ! (x && y); N z !X && (x && y); = !x && Y; N none of the...
a software training program is divided into training modules and each module is described by module name and the appropriate practice time. Each module sometimes has prerequisite modules. Model this situation of training programs and modules with an E-R diagram.
Write a JAVA program that declares a class Pet With three variables Name, Age, weight .The class has different constructors the first without parameters ,the second with three parameters and the third with two parameters. In the main method create three objects using thee different constructors to initialize the Variables. then print out all the information a bout all objects .

8. Each of the following heuristics helps make a good module according to some implementability or aesthetic principle. Identify the principle. (1) Provide get and set methods for all attributes in a class that clients might be interested in, even if they are not all used in the current program. (2) Do not reuse variables to hold different data. (3) Avoid operations with only a single line of code. (4) Keep operation parameters to five or less.
